From 253aa11578c1b89757282430891bb66ae5300092 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 20 Mar 2006 22:23:35 -0800 Subject: [PATCH] [IPSEC] xfrm_user: Kill PAGE_SIZE check in verify_sec_ctx_len() First, it warns when PAGE_SIZE >= 64K because the ctx_len field is 16-bits. Secondly, if there are any real length limitations it can be verified by the security layer security_xfrm_state_alloc() call. Signed-off-by: David S.
